The vulnerabilities won't go away on my system, either. They are due to Crestron panels running on old Android versions and requiring outdated packages, from what I was told.
Also, I would use npm install @crestron/[email protected] because the latest version isn't working correctly. Same for webxpanel - version 2.5.0 seems to work.
I recommend this blog - kielthecoder.com for a bunch of practical hands-on stuff. If you search ch5, html 5, and javascript on his page, he has several informative articles where he talks you through a lot of this stuff.
The r/crestron Reddit has some good info also.
